FREEMAN oass or BROOKLYN, new Y FEED-ROLLER FOR SPINNING MECHANISM.

Specification of Letters Patent.

. Application filed April is, 1920. Serial in. 373,516.

To (132 whom it may concern:

I Be it known that l, FREEMAN (Jess, a

citizen of the United States, and residing at Brooklyn, Kings county, State of New York, have invented certain new and useful Ims provements 1n Feed-Rollers for bpinnmg ll lechanism, of which the following is a specification. D

This invention relates to thread spinning machines and particularly to various de tailed improvements in certain of the feed rollers employed in such machines.

In machines of the kind mentioned it has been found advantageous to use rollers and other thread engaging parts made of porcelain. This material resists the wear or cutting action of the threads to a greater extent than metal and its glazed surface remains smooth, thus minimizing the tendency of the rollers to catch the threads and break the same which results in wastage of material, particularlywhen the ends of the threads become entangled in the gears and other parts of the machine.

It is the aim of the present invent1on to provide means for improvingthe operation of the rollers in machines of the kind referred to, particularly when porcelain rollers are employed. One ofthese objects is to provide an arrangement by wlnch the threads as they pass about the rollers are held away from the gears which drive the rollers and are prevented from catching between the ends of the rollers and the gears, so that the loss of material and inconvenience occurring by the entanglement of the threads with the gears may belargely avoided. Another object is to provide the surface of the rollers with a groove extending longitudinally thereof for a purpose hereinafter pointed out, and a still further object of the invention isto provide a speclal means for mounting the roller, such meanscomprising a bushing made of wood which, as will later appear, is of particular value in connection with porcelain rollers.

With these and other objects in view the invention is set forth in the following speci iication and embraced in the appended claims and the same is lllustrated 1n the accompanying drawings 1n wh1ch:

Figure 1 is a view in elevation illustrating the general arrangement of apart of a machine to which the present invention is applied;

Fig. 2 is a plan view illustrating the position and arrangement of the rollers employed in such machines and also showin the manner in which the threads are carried about such rollers;

F 1g. 3 is a longitudinal sectional View through one of the rollers involving the present invention; Fig. lis aperspective View of one of the improved rollers of the present invention;

1* 1g. 0 1s a transverse sectional view along the hue 5-5 of Fig. 3.

Referring to the drawings in detail the numeral 10 represents a series of spools which carry the supply of threads to be used in the machine. These threads after passing a guide member 1.1 are carried around the feed rollers and after passing such rollers are led into the other parts of the machine which have no relation to the present invention and which it isunnecessary to illustrate or describe. The rollers madeaccording to the present invention are mounted in a suitable frame 12, there being two of such rollers carried. in each frame. The rollers are mounted on spindles 13 which are arranged in suitable bearings 14 formed in the frame, and a gear wheel 14, driven in any suitable manner, cooperates with gears secured to the rollers in amanner later described.

The two rollers are identical in construction and a description of one of them will be suflicient. Referring particularly to Figs. 3 and at of the drawings it willbe noted that the roller proper designated by the numeral 15, is of tubular form and it is to be understood that such roller is made from porcelain having the outer surface thereof glazed which, as heretofore pointed out, effectivel resists wear by the threads, and since suc glazed surface is smooth and free from projections the threads are not liable to catch upon such surface and be broken. One feature of the present invention consists in providing a groove 16 which extends longitudinally of the roller. This becomes of value Patented Feb. 1, 1921.

in case the threads are broken and wound surface of the roller resulting in the formation of minute pro ectmns or a roughened portion which would tend to catch and break preferably made of wood is inserted in the bore of the roller, such bushing being providedlwith a suitable groove 18 for engaging the rib formed on the inner surface of the roller 15. The bushing 18 is suitably mounted upon the spindle 13 to which reference has already been made.

The bushing 18 is so arranged as to extend some distance beyond the end of the roller 15 and on such projecting end of the bushing a socket member .19 is mounted this socket member 19 being secured to the bushing in any suitable manner, as by frictional engagement ofthe parts so that as said member is caused to rotate the bushing and the roller. will rotate therewith. V A gear wheel 20 is non-rotatably mounted upon the socket member 19, this gear wheel constituting means by which the roller is rotated. As heretofore noted, each of the rollers mounted in the frame 12 are so arranged that their gear wheels 20 will contact with and receive motion from a common driving gear 14.

- It will be observed that the socket member 19 is made up of three portions, the bearing or gear supporting portion 19, which is'mounted on the bushing 18, the web portion 19 which extends outwardly at right angles to the portion 19 and the outer annular portion 19, part of which is adapted to surround and'closely fit the outer surface of the roller inserted in the socket. The outer edge or periphery of the annular portion 19 adjacent the gear wheel 20 is substantially flush with the outer ends of the teeth of this wheel and the outer surface of said portion 19 is inclined from a point adjacent the gear wheel inwardly I toward the opposite side or, in other words,

said surface is inclined outwardly with reference to the outer surface of the roller mounted within this member. The provision of such inclined surface arranged around the end of the roller adjacent the gear wheel constitutes an important feature of the present invention since it tends to keeplthe threads away from the gear wheel thus preventing entanglement of the threads inthe gear teeth or catching of the same between the end of the roller and the gear wheel.

The foregoing construction constitutes simple and effective means for securing together the roller and gear wheel and for providin the inclined surface surrounding the roller adjacent the gear wheel. It is obvious, however, that a collar or similar portion corresponding to'the annular portion 19 of the member 19 may be secured in position in other ways and that various other chan es in construction may be resorted to without departing from the spirit of the invention.

As heretofore noted, the bushing 18 is made of wood, the purpose of which, as has already been indicated, is to enable such. bushing to be securely fastened to the porcelain roller 15. ticles of porcelain the parts are apt to become more or less distorted or roughened and in order that a roller made of porcelain such as that heretofore described may be tightly secured to a bushing, it is necessary that the bushing be made of material which will yield more or less and accommodate it self to any unevenness or irregularity in the bore of the roller. Obviously, a metal bushing will not answer this purpose. On the other hand, it has been found that porcelain rollers of the kind described can be securely and satisfactorily mounted on bushings made of wood by forcing the rollers upon the bushings.

. Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
